CSS implements single-line, multi-line text overflow display ellipsis

If you realize the overflow display of a single line of text, you should all know that you can use the text-overflow:ellipsis attribute, and of course you need to add the width attribute to be compatible with partial browsing.

Implementation:

 

overflow: hidden;
text-overflow:ellipsis;
white-space: nowrap;

The effect is as shown in the figure:

But this property only supports the overflow display ellipsis of single-line text, what if we want to implement multi-line text overflow display ellipsis.

Next, let's focus on multi-line text overflow and display ellipsis, as follows.

Implementation:

display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 3;
overflow: hidden;

The effect is as shown in the figure:

Scope of application:
This method is suitable for WebKit browsers and mobile terminals due to the use of WebKit's CSS extension properties;

Note:

1. -webkit-line-clamp is used to limit the number of lines of text displayed in a block element. To achieve this effect, it needs to combine other WebKit properties. Common binding properties:
2. display: -webkit-box; A property that must be combined to display the object as a flexible box model.
3. -webkit-box-orient A property that must be combined to set or retrieve the arrangement of the child elements of the flexbox object.

Implementation:

p{position: relative; line-height: 20px; max-height: 40px;overflow: hidden;}
p::after{content: "..."; position: absolute; bottom: 0; right: 0; padding-left: 40px;
background: -webkit-linear-gradient(left, transparent, #fff 55%);
background: -o-linear-gradient(right, transparent, #fff 55%);
background: -moz-linear-gradient(right, transparent, #fff 55%);
background: linear-gradient(to right, transparent, #fff 55%);
}

The effect is as shown in the figure:

Scope of application:
This method has a wide range of applications, but ellipsis will also appear when the text does not exceed the line. This method can be optimized in combination with js.

Note:

1. Set height to an integer multiple of line-height to prevent excess text from being exposed.
2. Add a gradient background to p::after to avoid half of the text.
3. Since ie6-7 does not display content content, add tags to be compatible with ie6-7 (eg: <span>…<span/>); for compatibility with ie8, replace ::after with :after.
